As reporter earlier, Kangta has returned as a producer for the upcoming SBS drama ‘Wind Blows in Winter‘ OST, and teamed up with Super Junior‘s Yesung for the first song release!

The song is titled, “Carbon Paper“, and is described to be a pop ballad that portrays the sad love between Oh Soo (Jo In Sung) and Oh Young (Song Hye Gyo) with the help of Yesung’s soft vocals and Kangta’s emotion-packed lyrics.

It also serves as one of the main theme songs of the drama, so you’ll be sure to hear it often as you watch the drama premiere (on the 13th).
